belingstrips of this material.

While I shall hereinafter refer to the machine and describe its use in connectionthe expenditure of time, and more accu rately prepare the packet for market.

The invention consists essentially in a machine embodying three co-actin devices, 6. e., a reciprocating device for folding a strip of paper inlayers, a device for.rolling the folded strip of paper actuated through oscillatable members and wrapping a label about the rolled paper, and arotary label feeding device. These devices are actuated with predetermined relation to each other so that after the first step of folding the paper strip is completed, the rolling action immediately takes place, and, at the completion of this rolling movement the packet is wrapped in its label. In this manner a strip of crepe paper is fed to the machine and automatically folded, rolled into a packet, wrapped, and labeled and emerges from the machine in marketable form.

In the accompanying drawings I have illustrated one complete example of the physical embodiment of my invention constructed according to the best mode Ihave so far devised for the practical application of the principles of the invention Figure 1 is a side elevation of a machine embodying the novel features of my invention. Fig. 2 is a plan view of Fig. 1 with the driving mechanism omitted for convenience of illustration. Fig. 3 is a rear end View of the machine, being the end from which the wrapped packet emerges. Fig. 4 is an enlarged longitudinal, vertical scc t-ional view of the machine with carriers 1 omitted. Fig, 5 is a transverse vertical section of the machine. Fig. (3 is a view showing in detail the manner of folding the strip in layers on thereciprocating table. Fig. 7 shows an adjustable tappet. Fig. 8 shows a folded, wrapped and labeled packet of crepe paper, as it leaves the machine ready for the market.

At the present time, so far as I am aware, the crepe paper is generally folded and Wrapped by hand, in the mills. My machine is to be attached at the rear end of a crping machine in which the paper is creped, and after the paper is creped it is cut into suitable lengths, say 10 feet, and these strips of this length, or of other desirable length, are ready to be fed to my improved machine for folding. wrapping and labeling.

In the preferred embodiment of my invention I employ a table 1 having the side walls 2, 2, and open at the ends, which table is supported upon the legs 3, 3, the whole preferably being constructed of metal.

upported to reciprocate horizontally of this table 1 is a carrier 4 upon which the strip 5 is folded in layers as it is fed from the two feed rollers 6 and 7. At its underside the carrier is provided with a rack bar 8 having teeth 9 that mesh with the teeth of a rack Wheel 10 journaled on the shaft 11. The rack bar 8 is adapted to reciprocate in a slot 12 provided for the purpose in the table, and is actuated from the rack wheel 10 as will be described. 1

The rolling device which rolls the folded crepe paper into a packet includes an apron or belt 13 of fabric or other similar flexible material one end of which is fastened to the table and the other end of this apron is attached to a roller 14 on the shaft 15. The shaft 15 extends transversely across the table and extends or projects through a longitudinal slot 16 in the side walls 2 of the table and through and beyond slots 17in a pair of oscillatable side arms 18 which are pivotally supported upon the shaft 35. These side arms oscillate on the shaft 35 and in this manner provide an oscillatable device to cause the shaft 15 to travel longitudinally over the faceof the table, guided in the slots 16 and 17. The shaft 15 is rotated through the medium of a pinion 20 or rack Wheel fixed thereon and adapted to engage the teeth of a fixed rack bar 21, attached at one side of the table to its wall 2. By means of the engagement of the rack wheel 20 with its fixed rack bar 21 'theapron 13 is wound or wrapped about the roller 14 as its shaft is caused to travel in the slots of. the sides of the table and the altitude of the roller 14 above the folded layers of paper causes the apron to roll over the layers, starting by lifting the left edge or end in Fig. 4, and the continued movement of the apron causes the layers to be tumbled and rolled to the right end of the table to be handled'by an attendant, and the folded layers of crepe paper are rolled into a packet' In Fig. 2 it will be seen that the apron lies between the two side bars 4, 4" of the carrier and that these bars are connected by transverse bars 4 (dotted lines). This construction permits the crepe paper to be laid in folds between the side bars 4' with the edges'of the paper resting thereon, and in position to be gathered .up by the apron as it is Wound upon the .roller 14 as described.

The wheel 10 which causes the reciprocation of the carrier is actuated from a crank shaft 22 supported in the frame23 and hav. ing an eccentric 24. a The eccentric 24 is connected by rod 25 to the link 26 pivoted on the shaft 19 and carrying at its free end a pawl 27 in engagement with the rack wheel 28 on the shaft 19. .The rack wheel28 is in tegral with or fixed to a disk 29 on the shaft 19, and as the connecting rod 25 is reciprocated by the eccentric 24 the link 26 is rocked on its shaft 19 to revolve the disk 29 through the pawl and rack connection 27, 28. The

disk 29 is located adjacent the wheel 10 and has a series of pins or. studs 30,. fourteen in number as illustrated, located at regular intervals about the edge of the periphery v of thedisk, but it will be noted'that the stud 30 is nearer to the edge of the disk than the remainder of the series, for a purpose to be described. A tappet 31 is fixed on the shaft 11 in the path of movement of the studs or pins 30 on the disk 29, and a weight 32 is supported by its belt 33 over a drum 34 on the shaft 11. By these two devices, the series of'studs contacting with the tappet and the weight 32 the shaft 11 with its wheel -10 is revolved alternately anti-clockwise and clockwise, and the movement of the wheel causes the carrier to reciprocate horizontally as will be understood.

The side arms 18 are oscillated on their pivots 35 once to each revolution of the disk- At the opposite side of the.

supported between the two arms 18. ,This

shaft 38 has a pinion 39 which engages a pinion 40 on the shaft 35, and as the stud 36 strikes. the tappet 37 theshaft 35 .is ranked through the two pinions, and the rocking of 18 and the parts carried thereby." The arms.

7o the.shaft sw ngs or oscillates the twoarms 18 are returned to position througliithe medium of a counterweight 41 which has a belt'42 passing over pulley/t3 supported" in brackets on the machine and attached to a drum 44 on shaft-35.

The labels 45 are fed from a roll or reel 46 suspended transversely over the table of the machine by the feed rollers 47. One of the'feed rollers carries a knife 48 and pasting felt strip 49, the latter adapted .to receive paste from a roller 50 ha reservoir 51.

In Fig. 7 an enlarged detail of the tappet 31 is illustrated to show the means of ad usting it with relation to the shaft 11 and the pins 30. For this purposethe tappet isprovided with a large slot 52 and a pair of smaller slots 53, in which the set "bolts 54 are located and by which the tappet is clamped in adjusted position to the wheel 10.

In Fig. 5 the two supporting shafts 55 and 56 for the label feed rolls 47 are shown with gears 57 58 and a driving pulley 58,

which may be drivenby belt 59 (dotted lines Fig. 4) pulley 60 and belt 61 from the shaft of the paper feed roll 6. I

The completed packet is illustrated in Fig. 8 and designated by the number 62, the label 45 being neatly and tightly fastened thereabout. h

- The modus opemmli of the machine .is as follows: The machine is driven' by power from the shaft 22 as described and the gear wheel 10 is rotated by the action of the pins 30 striking the tappet 31 to rotate the shaft 11. It will be noted that the pin 30 is spaced a greaterdistance from the pins 30 than they are spaced from each other. This particular arrangement provides for a first layeror fold of greater length than the succeeding layers or folds of the strip 5, and the longer layer or fold which is at the bottom provides a Wrapper for the packet, about which the label is to be pasted."

The rotation of the wheel 10, causes the carrier 4 to move in one direction, and the weight 32 causes the carrier to move in the reverse direction each .time the tappet 31 is freed from a pin or stud 30. In this manner the carrier is caused to reciprocate causing the strip-of paper 5 as it is fed,'t0

fall in layers or folds on the'carrier. The pin 36 on the side of the disk opposite the studs or pins 30, is arranged to contact with.

the tappet 37 once to every revolution of the disk This action on the tappet 37 rocks the shaft 38 and through gears 39' and 40 the. oscillatable arms 18 are swung on their pivots 35. This oscillation of the arms,

causes the apron 13 to roll upon the roller 14 and the folded paper is rolled over as the apron rolls on the roller 14, until the rolled paper is carried over a waiting label 45, which has been fed from the roll 46 and has paste thereon ready to be sealed.

As the roll of crepe paper is rolled over the label and the label then rolled with the crepe paper, the label which has been gummed as previously stated is wrapped securely about the packet by hand, as shown in Fig. 8.
